Moreover, it seems promising to simulate the behavior of magnetic metamaterials based on artificial Josephson atoms in sufficiently strong fields [43] using standard classic software designed to study the magnetization reversal processes in large magnetic

For example, a simple planar periodic array of split-ring resonators (SRRs) provides magnetic resonances. Of particular interest is a stacked SRR dimer, in which

There is a difference between the artificially structured metamaterials (ASMs) [7] and our artificially structured light (ASL) [6]. In the case of ASM, artificial

We further show that the angular distribution of the far-field scattering of the spasing modes is by no means dipole-like and is very sensitive to the geometry of the structure.

• in the metal and due to radiative losses. However, a solution for this dilemma is possible because plasmons are Bosons and can hence be emitted via stimulated emission [24]. This might be used to minimize losses in metamaterials [25][26] and it has also been proposed for the compensation of losses in
